Fantastico Carholme, grazie mille !! 
Carholme many thanks. I was having no joy unearthing details surrounding this operation.
Ranger Helicopters Aérospatiale AS350B C-GBBX at the downtown Cherry Beach Heliport in Toronto in 1986 (Photo: The Mike Ody Collection)
From the photo notes: From August 1986 to June 1987 Air Canada leased three AS350 Astar's from Ranger Helicopters to operate a connector service between Toronto International Airport and Cherry Beach Heliport near Downtown Toronto.
And which brings me onto the next hurdle .. can anyone provide a little background information on Ranger Helicopters, where they were based and how long they operated for?
Plus .. if anyone has any memories of the Air Canada shuttle, please do chip-in!
